CONSTITUENCY BRIEFING · ENERGYMAP.APP
Henley and Thame
Henley and Thame has 151 MW of clean power (all solar) approved and still not built: enough to supply a year's electricity to 55,000 homes. Britain's grid bottlenecks still add to bills here: about £92 a year per household, £3.6m across the constituency's 39,348 homes. A 100 MW battery was refused planning here in 2025; while discharging it could have supplied about 350,000 homes.
Ranks 31 of 650 for clean power approved and not built.
